A forced reset trigger is only as reliable as the parts around it. The locking bar, the buffer, the bolt carrier group — these decide whether your reset is crisp every time or starts to feel mushy after a few hundred rounds. Forced Reset Triggers USA stocks the AR-15 and FRT support components that keep a forced-reset or Super Safety build running the way it should. Browse the full range of AR-15 trigger parts below.

Locking bars and FRT internals

The locking bar is the heart of an FRT's reset, and it is the part that wears first. The FRT-15 ALB Adjustable Locking Bar lets you tune engagement, and the Rare Breed FRT Locking Bar Performance Upgrade refreshes a trigger that has lost its snap.

Buffers and springs

Forced reset triggers want a heavier buffer than a standard carbine. An AR-15 H2 or H3 carbine buffer, paired with an enhanced buffer spring, gives the carrier the return energy a clean reset depends on. If your reset is inconsistent, this is the first place to look.

Bolt carrier groups

A full-auto-profile carrier is part of reliable forced-reset function. The BCM MPI Auto BCG covers AR-15 builds, and the Aero Precision .308 Winchester BCG handles large-frame rifles.

Selectors and receivers

Rounding out a correctly-specced build, the Radian Talon ambidextrous safety selector and an M16-cut lower receiver give you the right foundation for the triggers in our Rare Breed FRT and Super Safety lines.

Frequently asked questions

What buffer do I need for an FRT? An H2 or H3 carbine buffer is the standard recommendation.

Do I need a full-auto BCG? A full-auto-profile carrier is strongly recommended for consistent reset.

What does a locking bar do? It controls how the FRT resets; an adjustable or upgraded bar restores reliability as parts wear.

Will the BCM carrier fit my AR-15? Yes — it is a standard mil-spec AR-15 bolt carrier group.

Are these parts drop-in? Most are; receivers and a few fitting jobs are better left to a builder. For complete rebuild kits, see our upgrade kits.
